Use Transpose[] to get your points (please avoid initial capital letters for your symbols): In[1]:= a = {{x1, x2, x3, x4, x5, x6}, {y1, y2, y3, y4, y5, y6}}; In[2]:= ListPlot[Transpose[a]]; will get you what you want. If you have duplicate points in Transpose[a}, then In[3]:= Union[Transpose[a]] will get rid of them.
